@tronweb3/tronwallet-adapter-binance-evm

This package provides an adapter to enable DApps to connect to the Binance Wallet App.

Demo

import { BinanceEvmAdapter } from '@tronweb3/tronwallet-adapter-binance-evm';

const adapter = new BinanceEvmAdapter();
// connect
await adapter.connect();

// then you can get address
console.log(adapter.address);

// just use the sendTransaction method to send a transfer transaction.
const transaction = {
    value: '0x' + Number(0.01 * Math.pow(10, 18)).toString(16), // 0.01 is 0.01ETH
    to: 'your target address',
    from: adapter.address,
};
await adapter.sendTransaction(transaction);

API

• Constructor(config: BinanceEvmAdapterOptions)

  import { BinanceEvmAdapter } from '@tronweb3/tronwallet-adapter-binance-evm';
  interface BinanceEvmAdapterOptions {
      /**
       * Set if open Binance Wallet app when in mobile device.
       * Default is true.
       */
      useDeeplink?: boolean;
      /**
       * Set if open Wallet's website when wallet is not installed.
       * Default is true.
       */
      openUrlWhenWalletNotFound?: boolean;
  }
  
  // Default: open the Binance Wallet app on mobile, and open the wallet website
  // when the wallet is not detected.
  const adapter = new BinanceEvmAdapter();
  // Stay on the current page on mobile instead of opening the Binance Wallet app.
  const withoutDeeplink = new BinanceEvmAdapter({ useDeeplink: false });
  // Do not open the wallet website when the wallet is not detected.
  const withoutWebsite = new BinanceEvmAdapter({ openUrlWhenWalletNotFound: false });
  // Never navigate away; handle both cases in your own UI.
  const silent = new BinanceEvmAdapter({ useDeeplink: false, openUrlWhenWalletNotFound: false });

  How the two options interact

  connect() evaluates the deeplink first, so at most one of them takes effect per call:

  1. In a mobile browser where neither the Binance Wallet extension nor the Binance in-app browser is detected, and when useDeeplink is not false, the adapter opens the Binance Wallet app and connect() resolves with an empty string immediately. openUrlWhenWalletNotFound is never reached.
  2. Otherwise — on desktop, inside the Binance Wallet in-app browser, or with useDeeplink: false — the adapter looks for the injected provider. If it is missing and openUrlWhenWalletNotFound is not false, the wallet website is opened in a new tab, and WalletNotFoundError is thrown either way.

  So openUrlWhenWalletNotFound only applies on the path where no deeplink was opened.

Caveat

• Currently Binance wallet app does not support addChain().
